Engineered for space-constrained applications, the 6811-ZZ is a single-row, thin-section deep groove ball bearing from the 6800 series. It features non-contact steel shields on both sides that hover just above the inner ring, providing a low-friction physical barrier against external debris. Despite accommodating a substantial 55 mm shaft, its exceptionally slim 72 mm outer diameter and 9 mm width minimize the overall footprint and weight of the rotary assembly. This unique geometry makes the 6811-ZZ the optimal solution for advanced mechanical designs—such as robotics and automated drive systems—where standard-sized bearings would add unnecessary bulk and mass.
